Separate Herald transcripts into several different views

Summary: Ref T13586. The Herald transcript page has become more and more complicated over time, and recently added "Transactions" and "Profiler" sections. Split these across separate navigation tabs to limit the maximum complexity of any single view and make it easier to navigate to particular sections, like the profiler section.

Test Plan: Viewed various transcripts, saw nice digestible sections.
